2. ANATOMY OF THIGH
Thigh is the area between
the pelvis and the knee.
The single bone in the
thigh(femur).
Thigh is divided into
three compartment. This
is separated by
fascia(fascial septa).
Anterior ,posterior and medial.
5. POSTERIOR COMPARTMENT
MUSCLES
Hamstrings
Biceps femoris.
long head.
Short head.
Semimembranous.
Semitendinosus.
Adductor magnus.
INNERVATION
Common peroneal nerve(short head).
Sciatic nerve(L4,5,S1,2,3).
ACTION
Hip extension.
Knee flexion.
6. TENSOR FASCIA LATA
The fascia lata is thickened laterally ,
this is tough fibrous sheath that
envelops the whole of the thigh like a
sleeve.
Its continuation a 5 cm wide band
called iliotibial tract.
Iliotibial tract stabilizes the knee both
in extension and in partial flexion.
The tract I is the main support of the
knee against gravity.
7. FEMORAL TRIANGLE
it is a triangular depression on the front of
the upper one –third of the thigh
immediately below the inguinal ligament.
It is bounded laterally by the medial border
of sartorius; medially by the medial border
of the adductor longus; its base is formed
by the inguinal ligament.

femoral nerve
Femoral artery
Femoral vein
Lymphatics
8. INJURIES
CONTUSIONS
HIP POINTER
A hip pointer generally refers to a contusion of the iliac
crest over the tensor fascia latae muscle belly with an
associated hematoma, but the term also may be used to
identify tearing of the external oblique muscle from the
iliac crest, periostitis of the crest, and trochondric
contusion.
Mechanism
A direct blow impacts the iliac crest.
9.
10. QUADRICEPS CONTUSION
The most common site for a this contusion is the anterolateral
thigh.
If the contusion is located adjacent to the intermuscular septum,
pain and hemorrhage tend to resolve more rapidly.
Associated with greater tearing, hemorrhage, and pain with great
tendency toward abnormal pathology.
Signs and symptoms
Pain and swelling immediately after impact(grade1) able to walk
without a limp, passive flexion beyond 90 degree may be painful,
but resisted knee extension may cause less discomfort.
Grade 2: flex the knee between 45 to 90 degree and walk, swelling
prevents the knee fully flexed.
Grade 3: bruising seen initially, but within 24 hours, progressive
bleeding and swelling occur, firm hematoma, resulting in an
inability to contract the quadriceps or do a straight leg raise.
11. MYOSITIS OSSIFICATION
abnormal ossification involving bone deposition within muscle tissue. It may
stem from a single traumatic blow, or from repeated blows, to the quadriceps.
Risk factors:
Innate predisposition to ectopic bone formation.
Continuing to play after injury.
Early massage, hydrotherapy, or thermotherapy during the acute stage.
Passive, forceful stretching.
Too rapid a progression in the rehabilitation program.
Premature return to play.
Re-injury of same area.
Common sites are the anterior and lateral thigh. Although the precise
mechanism that triggers the bone formation has yet to be established, it is
thought that during resolution of the hematoma,within a week after injury, the
existing fibroblasts involved in the repair process begin to differentiate into
osteoblasts.
Signs and symptoms
A warm, firm, swollen thigh nearly 2 to 4 cm larger than the unaffected side.
Painful mass may limit passive knee flexion to 20 to 30 degree.
Quadriceps contraction and straight leg raise may be impossible.
12. ACUTE COMPARTMENT SYNDROME
This is advance stage of the quadriceps contusion.
Defined as increased tissue pressure in a facial
compartment that compromises circulation to the
nerves and muscles within that compartment.
A result of crushing injury or fracture of the
femur.
Signs and symptoms
Severe pain occur with passive motion and
isometric contraction of the quadriceps.
Motor weakness and decreased femoral sensation.
13. STRAINS
Quadriceps strain
This strain is less common than hamstring strain.
Tears more commonly occur in the mid-substance
muscle belly of the rectus femoris, because this is
most superficial.
Vastus medialis and lateralis are more rarely injured.
14. HAMSTRINGS STRAIN
The hamstrings are the most frequently strained
muscles in the body, and these strains typically
are caused by a rapid contraction of the muscle
during a ballistic action or a violent stretch.
Risk of injury
Lack of neuromuscular control
Overuse
Muscle fatigue
Improper technique and warm-up.
15. ADDUCTOR(groin)STRAIN
Adductor strain are common in activities requires quick changes
of direction as well as explosive propulsion and acceleration.
A strength imbalance between the hip abductors and adductors
may be a predisposing factor in many of these injuries.
The more severe strains typically occur at proximal; attachment
of adductor longus.
Signs and symptoms
Sharp pain
Stiffness
Weakness in adductors.
Increased pain during
• Side-to-side movement
• Passive stretching
• Abducted position
• Externally rotated and with resisted hip adduction.
16. PIRIFORMIS SYNDROME
The sciatic nerve passes through the sciatic notch beneath
the piriformis muscles to travel into the posterior thigh.
The nerve to compression from trauma, hemorrhage, or
spasm of the piriformis muscle, most commonly peroneal
part of nerve is compressed.
Signs and symptoms
Low back pain is not usual
Difficulty in walking up-stairs
Weakness or numbness present in back of the leg.
pain and weakness present in hip external rotation.
SLR may be limitted.
17. STRESS FRACTURE
Stress fractures of the pubis, femoral neck, and proximal
third of the femur are seen in individuals who engage in
extensive jogging or aerobic dance activities to the point
of muscle fatigue. Several factor increase the risk of stress
fracture
Improper footwear.
Biomechanical abnormalities.
Change in the running surface or terrain.
Sudden increase in training.
Signs and symptoms
Aching pain in the groin or thigh, during weight bearing.
Night pain.
Antalgic gait.
18. OSTEITIS PUBIS
osteitis pubis is an inflammatory process involving
continued stress on the pubic symphysis from
repeated overload of the adductors muscles or
repetitive running activity.
Signs and symptoms
Pain in the adductors
Pain aggravating to the kicking, running and
pivoting on one leg.
Pain radiating distally into medial thigh.
19. FEMORAL FRACTURES
Fractures of the femoral shaft can be very
serious because of potential damage to the
neurovascular structure from bony fragment.
Causes: tremendous impact forces, shearing
force or torsion force, direct compressive force.
Fracture may be open or closed.
27. THIGH GIRTH
Proximal or upper girth: About 1 cm below the
gluteal fold and horizontal to the long axis of
femur.
Mid thigh: measurement is taken from
inguinal crease to the proximal border of
patella.
Distal thigh: it is measured from just proximal
to femoral condyles.
